Change your mind, not your time. Seneca, Epistles 3.28.1-3

Seneca answers a letter from Lucilius in which the latter asked why his vacations abroad failed to improve his life, philosophically speaking. Seneca points out that changing location is not the same as changing our internal condition. We cannot control the weather outside, but the weather in our minds is something over which we have significant control, if we can learn to grasp it.


Hoc tibi soli putas accidisse et admiraris quasi rem novam quod peregrinatione tam longa et tot locorum varietatibus non discussisti tristitiam gravitatemque mentis? Animum debes mutare, non caelum. Licet vastum traieceris mare, licet, ut ait Vergilius noster,

      terraeque urbesque recedant,

sequentur te quocumque perveneris vitia. Hoc idem querenti cuidam Socrates ait, 'quid miraris nihil tibi peregrinationes prodesse, cum te circumferas? premit te eadem causa quae expulit'. Quid terrarum iuvare novitas potest? quid cognitio urbium aut locorum? in irritum cedit ista iactatio. Quaeris quare te fuga ista non adiuvet? tecum fugis. Onus animi deponendum est: non ante tibi ullus placebit locus. Talem nunc esse habitum tuum cogita qualem Vergilius noster vatis inducit iam concitatae et instigatae multumque habentis se spiritus non sui:

      bacchatur vates, magnum si pectore possit
      excussisse deum.


Do you really think that the disappointing outcome of your recent vacation is so unique? Are you amazed at it, as though it were utterly unexpected that you should travel so long, to so many different places, without managing to shake the sadness that weighs upon your mind? Your duty on life's journey is to manage your mind, not the weather you meet. Suppose you cross a vast ocean, so great that as our own Vergil says,

      Shores and cities fall from sight.

Aeneid 3.72 ()

Still your vices will come with you wherever you go. Someone once asked Socrates the same question you put to me. The philosopher said, “Why are you surprised that your travels avail you nothing, since you always take yourself along? When you arrive at your destination, you are still pressed by the same internal circumstances that drove you out of your home.” What help is it to be in another country? How does knowing different cities or lands improve your relationship to yourself? Taking yourself all over the world does nothing for your mind. You want to know why your vacation abroad is useless, why it gives you no relief? It's because you are taking it with yourself. Your mind carries within a burden that it must put down: until this happens, no place will bring you peace. You must imagine your condition now as being very similar to that of the prophetess Vergil describes, pricked and goaded by a spirit that is not her own:

      Wild she longs with mad delight
      From her chest the god to strike.

Aeneid 6.78-9 (†)

---
() These lines are uttered by Aeneas to the Carthaginian queen Dido, as the hero recounts how he and his people first set sail for foreign lands after the Greeks captured Troy, their home.

(†) The prophetess here is the Cumaean Sibyl, and the god she struggles with is Apollo. Ultimately, she reveals to Aeneas the fate of his band of refugees from Troy.
